Comparisons of 18F-THK-5351 uptake patterns among the SUVR map and Z-maps at multiple Z-score thresholds. A patient with a lacunar infarct at the right internal capsule (a, b) shows increased 18F-THK-5351 uptake around the stroke lesion on the SUVR maps (c, d). On the Z-maps with sequentially increasing thresholds, the 18F-THK-5351 uptake regions gradually shrink (e–h). Furthermore, the increased 18F-THK-5351 uptake might extend to the cerebral cortex without corresponding changes observed on the conventional FLAIR and DWI images
